IMPROVEMENT IN DRAFT-'EQUALIZERS FOR` WAGONS.

Specification forming part of Letters Patent No. 217.138, dated July 1, 1879; application iiled April 28, 1879.

To It whom it may concern:

Be it known that I, BENQT. C. NELsEN, of De Kalb, in the county of De Kalb, in the State of Illinois, have invented a new and useful Improvement in Wagons, ot' which the followingI is a specification.

This invention relates to an improved construction of the tongue and double-tree supporting devices of wagons and carriages.

In the accompanying drawings, Figure l is a plan, and Fig. 2 a side, viewof a part ofthe wagon embracing my improvements. Fig'. 3 is acentralsection of the same with the tongue removed, and Figs. 4 and 5 are detail views y ofthe hammer-strap and its attachment.

In the drawings, A is the tongue; B, the axle; 0,the bolster, and D D the hounds. The tongue is not secured directly to the axle, but is pivoted upon a horizontal bolt, a, passing through it and the forward ends ot' the hounds. It extends back from this pivot some distance, and is held from lateral motion by the parts D of the hounds upon either side. This backward extension also serves as acounterbalance to the portion ofthe tongue forward of the pivot.

The double-tree E is sustained upon the" hounds below. It is intended that the slots g shall permit some back and forward play to the plates G.

To receive the wear caused by the plates G, bed-plates H may be put upon the hounds'.

Draft-chains I extend from the axle ends to the plates Gr, and are attached to ears g upon the latter. They receive the strain of the pull upon the doubletree. The play afforded by slots g in plates G allows the double-tree to work back and forth to a limited extent, as is desirable.

l do not confine myself to V-shaped ham- 1nerstraps,ot' course, as it is evident that any form ot' strap which will permit attachment to the hounds at either side and hold the hammer at the center will answer the purpose.

I am aware that the double-tree has heretofore been supported from the under side ofthe hounds and independently ot' the tongue. I place it upon the top' of the hounds, and thereby am enabled to simplify the fastening, as

'by a hammer and strap, the latter of which is attached to both of the hounds by sliding plates secured to and having a limited movement upon the latter, in combination with the hounds, sliding plates, hammer, and strap, substantially as set forth.
